----------------------------------

             Summary: Support to run a TableAPI query like 'table.select('a, 'b, 'c)'
                 Key: FLINK-12810
                 URL: https://issues.apache.org/jira/browse/FLINK-12810
             Project: Flink
          Issue Type: Task
            Reporter: Jing Zhang


Support to run a TableAPI query like 'table.select('a, 'b, 'c)', including:
1. add RexNodeConverter to convert Expression to RexNode
2. Introduce RexPlannerExpression to wraps a RexNode, which is similar to RexPlannerExpression in flink-planner module.
3. add QueryOperationConverter to convert QueryOperation tree to RelNode
4. Introduce PlannerQueryOperation to wraps a RelNode in QueryOperation, which is similar to PlannerQueryOperation in flink-planner module.
5. add OperationTreeBuilder and relative classes(ExpressionResolver, TableReferenceLookup, FieldReferenceLoopup, ExpandColumnFunctionsRule, LookupCallByNameRule, ResolverRule, StarReferenceFlattingRule, VerifyNoUnresolvedExpressionRule), which is almost copy from flink-planner module to blink-planner module, except that we remove dependency on PlannerExpression. **Note: This is temporal solution, since OperationTreeBuilder will be moved to api module finally.**
6. add implicit conversion in expressionDsl
